[Solved] Client Side RowClick - Index outside the bounds of the array

[Reuven]

Have no idea what it would take to reproduce this, but basically had a grid that had the rowclick event working until I manipulated a details table on prerender significantly (hide it for example if there is no data). Now when I click on a item on the mastertable, I get a:

Error: Sys.WebForms.PageRequestManagerServerErrorException: Index was outside the bounds of the array.

The eventArgs.get_itemIndexHierarchical is set to the correct row, the mastertableview has the correct number of "get_dataItems()".

Please let me know what I can send to help clarify the problem.

Thanks,

I've been able to narrow it down to a problem simply accessing GetItems in PreRender

        Protected Sub RadGridSpecialtyProblemList_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGridSpecialtyProblemList.PreRender
            For Each item As GridDataItem In RadGridSpecialtyProblemList.MasterTableView.Items
                If item.HasChildItems Then
                    Dim nestedtable As GridTableView = item.ChildItem.NestedTableViews(0)
               ===> Dim footer As GridItem = DirectCast(item.ChildItem.NestedTableViews(0).GetItems(GridItemType.Footer)(0), GridFooterItem)
                    Dim ddlStudies As DropDownList = DirectCast(item.ChildItem.NestedTableViews(0).GetItems(GridItemType.Footer)(0).FindControl("ddlStudies"), DropDownList)
                    If nestedtable.Items.Count = 0 And ddlStudies.Items.Count = 0 Then
                        nestedtable.visible = False
                    Else
                        If ddlStudies.Items.Count = 0 Then footer.visible = False
                    End If
                End If
            Next
        End Sub

Basically have a DetailTable that shows "enrolled" studies for a particular problem (item in my mastertable). The footer on the Detailstable has a dropdownlist that is bound to the available studies (if a study is enrolled, then it does not show up on the ddl). So if there are no studies at all, I want to hide the detailstable completely. If there are no enrolled studies, but some available, I display the NoRecordsText, and show the footer. If there are enrolled studies, but none available remaining, then I want to hide the DetailTableFooter. The above code works perfectly, except that subsequent operations give an Index outside the bounds of the array error.

figured out my problem - didn't have to wait until PreRender to do this, but could just set everything on ItemDataBound. Conceptually, was missing that this event gets raised for all subitems in the grid, so just needed to check for the ownertableview.name and the itemtype and was set.
